' DELIVERY APPARATUS.

Application filed April 13, 1927. Serial No. 188,530.

This invention relates to new and useful improvements in deliveryapparatuses The principal object of the invention is to provide adelivery apparatus whereby-articles such asblocks of ice or any otherarticle, which, when supported on tracks,

have a tendency to hang or adhere thereto,

7 may be dislodged and caused to travel downward along saidltracks eventhoughthe latter are not disposed at a steep inclination.

Another object of the invention isto provide certain improvements inconnection with the delivery apparatus set forth in 'my co-pendingapplication, Serial No. 152,849 which has since matured 1,647,530,issued Nov. 11, 1927 a g F A particular objectof the invention is toprovide means operated by the, delivery mechanismforagitating the ice orarticles on the tracks prior todelivery to the chute. J

Aconstruction designedfto'carry out the invention will be hereinafterdescribed, to

gether with other features of the invention.-

The invention will be more readily understood from a reading. offthefollowing specificationand by referenceto the aceompany-' on the line 22of Fig. 1, I

Fig. 3 is a view similar to Fig. 1 showing the delivery and agitating''means in operative positions,

:Fig. 4 is a plan n Fig. 3,

. Fig. 5 is a side View showingiin ean portion of the displacement railinf tsnormal. position in full lines and in ts operativepositionin'dotted lines, 3

Fig, 6 is a plan view of the same, Fig. 7. is a cross-sectional viewtaken on the line '77 of Fig'. 6, and Fig. 8 is a detai of the leverconnection. In the drawings the numeral hers 11 are supported. Thesctracks are spaced apart and are. preferably made of T-raiia which areinverted so as to form singis -i runners. The track disposed at a Fig. 2isa transverse sectional view. taken nates in a handle 33.

sufiicient incline to cause blocks of, ice to slide down the same. Thelower ends of the members 11 are fastened to the bottom of an inclinedchute 12 by means of hangers 3 13. The chute is disposed at a muchgreater pitch than the track and is fastened on a pair of supportingmembers-14 of .suitable construction. The chute has side walls 12 and isprovided at its lower end'with a housing 15 having'a frame 16, whereby,it is secured in the wall 17 of thestructure in which the apparatus ismounted. The track.

members 11 have their'lower ends terminatspaced below the surface of thebottom of stop or abutment.

Blocks of ice, A, B and C, or other objects, 7

when placed on the track members 11 will slide down the same, the lowerfront edge of theblock A engagingv the stopf18, as is shown in Fig. 1.-Theblockswi1 l be held in i this position until the block A isdislodged- It will be seen that by elevating thefront .end of the blockA and moving it forwardly,

it will be deposited in the chute113 and will thus slide down the sameand be delivered.

On the members 12 I mount bearing boxes 19 in which a transverse rockshaft journaled. On the shaft-Ifasten a pair of split collars 21, eachhaving a pair of ears 22. "Between'eachj pair of ears, a dog 23 ispivoted on a pin24, as is shown in detall in Fig. 2. Each dog is taperedto a point and has atripping weight 25 at its opposite end. Theweightacts as a counter-balance, but the dog 23 has sufli- Y cientweight outwardly beyond the pivot 24 v I "to normally hold the weight upagainst view of the parts shown i the collar 21, as is shown infulllines in 'Figs. 1 and 3. The bottom of the chute 13 has slots 26extending downwardly from the edge 18 located over the dogs so that I I29 is provided with a shoulderedaxle 30 7 1O designates" a standard onwhich a pair of track inemcarrying a roller 31 enga edinfthe slot 28.

' if allowedz-to stand {any length-ftin-1e,-may

tend to adhere to the rails. "The tongues of the T-shaped rails have atendency to embed in the, under. sides of. the blocks. '[Fhisfcoul'd 1be overcome \to a great extentl'byigiving'athe track a greater pitch orinelination,but this would involve lifting the bloeks-ef 'iee a greaterheight to load thern onto the rear of the track and would also create agreater .pressure against the block A, which lrnust .be'glifted0nto'the1cl1ute'12.

In order to agitateor impel the blocks of'ice" I mount a riserbar orrail 85'between" TlllS rail 35 1s also pre'ferably T- 'shapedi andisinverted to form t a single runner. The riser rail rests at its forwardtheir forward ends'fastened to the sides 12 of the chute. t
